Too much timing...Too lean...Taken too much out of the low end of the VE table (400/800/1200)...Can you get the car logged? Codes? Mods?

Need more info.

Dont really have much of an answer, but my LT1 with a 230/244 cam did that too even after it was tuned It didnt do it after I swapped heads and went to a 240/240 cam. Maybe more tunning is needed?
